Y BALL-BEARING.

To alt whom it may concern:

Be it known that l', Enwann B. lli-zss, a eitizen of the United States of America, residing in the borough of hfanhattan, city, eounty, and State of New York, have, invented a new and useful Improvement in Ball-Bearings, of which the following is a specification. f

This invention coinprisesan organization wherein bearing halls traveling in a rat-eway areeach dianietiieally surrounded hy an annular gear that meshes with a rack or racks, the balls being thus maintained lin proper relative position with respect to each other and tothe movable part of the raceway. The annular or ring gears may he disposed vertically or otherwise. i

The accompanying drawing shows the invention applied to the hanging of sliding doors. lt is, however, useful in many other relations and the drawing is illustrative merely of one way in which the invention may he advantageously employed.

Figure 1 is an elevation showing a sliding door hung exterior to the frame: Fig. 2, an end view of Fig. 1 on a larger scale: Fig. a detail elevation showing the lower part of the race-way and a hall and.A its ring gear therein: Fig. 4, an elevation showing a door swung within the framerFig. 5, an end n elevation of Fig. 4: Fig. 6, a suetion on the line 6, 6, of Fig. 5: and Fig. 7, a detail view showing a bearing ball and its enoireling ring gear.

In Figs. l and 2, a indieates the fixed frame to which is Secured a braeket b shaped to constitute the lower half of a horizontal race-way and its upright outer edge formed with rack teeth c. (Z indicatesthe sus )ended door to which is secured a brac ret' c shaped to overlie the projecting partV of y Patented Jan. 11, 1910.

hraeket I, thus forming the upper halt` ot" I -the rare-way and having its' downwardiy extending edge formed withrack teeth f. 1/ indieates the bearing halls. eaeh of which is: surrounded with a ring gear li, the opposite. sides of which. mesh with the raeks o, v

'f. ln this ease the ring gears are disposed horizontally.

In Fig. 4, "there are hraeltets 1)', e' one overlying the other, thus forming a raee-t way and secured respectively to the frame a and sliding door J'. ln this ease, the ring gears encireling the halls engage apertures at the bottom and at the top of the i'iwe-way-the gears heilig disposed vertically. 'lhese apertures, in that part of the bracket e eonstitnting the.upper part of the raee-way, lare shown in the top view. Y

Fig. The apertures are mai-'lied i and constitute in effect and in faet a raek with whit-h the gears engage.

When the halls are loosely disposed within the ring gears, they are free to turn in any direction and there is. therefore. eliminated lateral strain on the gears. 'lhe organization is characterized hy great delieaey or ease of operation.

claim:

A ball hearing eoiuprising a hall rat-e, bearing halls therein. annular gears loosely eneircling the halls. and raelt's, one inovahle and the other stationary` respeetively enf gaged hy opposite sides of the gears.

ln testimony whereof. l have hereunto subscribed my name.
